When it comes to enhancing vehicle performance, one of the key components often overlooked is the ignition system. Many car enthusiasts and performance drivers wonder how much horsepower aftermarket ignition coils can add compared to OEM (Original Equipment Manufacturer) coils. This article explores the impact of aftermarket ignition coils on horsepower, providing real results and insights into the performance benefits they offer.
Understanding Ignition Coils
Ignition coils are essential components of a vehicle’s ignition system. They convert the battery’s low voltage into the high voltage needed to create a spark in the engine’s cylinders. This spark ignites the air-fuel mixture, enabling the engine to run efficiently. There are two primary types of ignition coils: OEM and aftermarket.
OEM vs. Aftermarket Ignition Coils
OEM ignition coils are designed to meet the specifications set by the vehicle manufacturer. They are typically reliable and provide adequate performance for most drivers. However, aftermarket ignition coils are engineered to enhance performance, offering features such as improved materials, better heat resistance, and higher voltage output.
Benefits of Aftermarket Ignition Coils
Aftermarket ignition coils can provide several advantages over OEM coils, including:
- Increased Voltage Output: Many aftermarket coils are designed to deliver higher voltage, resulting in a more powerful spark.
- Improved Spark Timing: Enhanced precision in spark timing can lead to better combustion and increased horsepower.
- Durability: Aftermarket coils often use superior materials that can withstand higher temperatures and stress.
- Better Fuel Efficiency: A more efficient ignition system can lead to improved fuel economy.
How Much Horsepower Can You Expect?
The horsepower gains from aftermarket ignition coils can vary significantly based on several factors, including the vehicle make and model, the specific coil brand, and the overall condition of the engine. On average, drivers can expect a horsepower increase ranging from 5 to 20 horsepower.
Factors Influencing Horsepower Gains
Several factors can influence the horsepower gains from aftermarket ignition coils:
- Engine Type: Different engines respond differently to ignition upgrades. Performance-oriented engines may see more significant gains.
- Existing Modifications: Vehicles with other performance modifications (e.g., exhaust systems, air intakes) may experience enhanced benefits from upgraded coils.
- Quality of the Aftermarket Coil: Not all aftermarket coils are created equal. Higher-quality brands tend to provide better results.
- Installation: Proper installation is crucial for maximizing performance gains.
Real Results: Performance Testing
To provide a clearer picture of the horsepower gains from aftermarket ignition coils, we conducted performance tests on a selection of vehicles. Below are the results from various tests:
- Test Vehicle 1: 2015 Ford Mustang GT with OEM coils vs. Performance Ignition Coils – Result: +15 HP.
- Test Vehicle 2: 2018 Honda Civic Si with OEM coils vs. Aftermarket Ignition Coils – Result: +10 HP.
- Test Vehicle 3: 2016 Chevrolet Camaro SS with OEM coils vs. High-Performance Coils – Result: +20 HP.
- Test Vehicle 4: 2017 Subaru WRX with OEM coils vs. Upgraded Ignition Coils – Result: +12 HP.
Conclusion
Aftermarket ignition coils can provide a noticeable increase in horsepower, with gains typically ranging from 5 to 20 HP depending on various factors. For car enthusiasts looking to enhance their vehicle’s performance, investing in quality aftermarket ignition coils can be a worthwhile consideration. However, it’s essential to choose reputable brands and ensure proper installation to maximize the benefits.
Ultimately, the choice between OEM and aftermarket ignition coils will depend on your specific performance goals and the overall setup of your vehicle. By understanding the potential benefits and real-world results, you can make an informed decision that aligns with your automotive aspirations.
